NUMECA Releases VNoise 5.1

Posted Wed February 22, 2012 @02:35PM

NUMECA International has released the acoustic simulation software VNoise 5.1.

VNoise 5.1 features direct import of meshes and results from FINE/Open and FINE/Turbo.

VNoise 5.1 also introduces the possibility to perform 2D analyses
with both the BEM and FEM modules, also allowing 2D FEM/BEM coupled analyses and 2D vibroacoustic analyses. This will save significant resources when analyzing problems that are inherently 2D.

Other minor changes include the possibility to decouple the
calculation period from the period of unsteady loads in FWH analysis,
eventually introducing a window to reduce leakage effects.
The feature can be useful for example in Counter Rotating Open Rotor (CROR) systems.
